Angular IE Caching issue for $http

Title: 💻 Fixing Angular IE Caching Issue for $http - Say Goodbye to 304 Responses!

Hey there, tech enthusiasts! Are you stuck in a cache-22 situation with your Angular app? 😩 Are you tired of seeing those pesky 304 responses, even though your requests and responses are not the same? Fear not, for we have some nifty solutions to resolve this pesky Angular IE caching issue for $http. Let's dive right into it! 💪🏻

🔄 Understanding the Angular IE Caching Issue

So, here's the scoop. Angular has this little habit of caching all ajax calls made from Internet Explorer (IE). And while caching is great for performance, it can be a real headache if your subsequent calls don't have the same response as the initial call. We get it, that's annoying as 🦆!

🔍 Digging Deeper into the Issue

If you've encountered this problem, you may have already tried adding the cache attribute to $http.get, only to find the issue persisting like a bad penny. What gives? 💔

The thing is, the cache attribute doesn't actually do much when it comes to IE. It's more like a red herring in this situation. So, we need to explore alternative solutions to steer clear of this caching conundrum.

💡 Solution 1: Disabling Caching Through Angular Config

One way to tackle this issue is by disabling caching through Angular's configuration options. 🛠️ You can do this by adding the following code to your app.config or run block:

app.config(['$httpProvider', function($httpProvider) {
  // Initialize the headers if not already set
  if (!$httpProvider.defaults.headers.get) {
    $httpProvider.defaults.headers.get = {};
  }
  // Disable caching globally for all $http calls
  $httpProvider.defaults.headers.get['If-Modified-Since'] = '0';
}]);

What this code does is send the 'If-Modified-Since' header as 0, effectively disabling caching for all $http calls. 🚫💾

💡 Solution 2: Adding a Random Query Parameter

Another effective solution involves adding a random query parameter to bypass Angular's caching behavior. 🙌🏻 By appending a unique value to each $http call, you trick Angular into thinking it's a different request, thereby eliminating the caching issue. Here's an example:

$http.get('your-api-url?random=' + Math.random())
  .then(function(response) {
    // Handle the response
  });

By generating a random number (Math.random()) each time the call is made, IE starts treating it as a new request, preventing any pesky caching issues from rearing their ugly heads. 🙅🏻‍♂️
